2. Dark Matter Dark matter is invisible matter that we can’t touch, or hear, or see at all. Dark matter makes up 80% of the universe It affects the rotational speeds of galaxies, the temperature distribution of hot gas, and the gravitational lensing of background objects(gravitational lensing is the curving of light because of the gravity of a very large object.)
3. Dark Energy Dark energy is a hypothetical form of energy that covers all of the universe. It is what increases the rate of expansion Dark energy makes up 73% of the energy in the universe Dark energy is not very dense and isn’t affected by gravity. Very little is known about dark energy
4. Similarities Obviously they both have “dark” in their names They both can’t be seen There is very little known about both They both make up a big percentage of the universe
5. Differences Dark matter is obviously matter, while dark energy is energy. Dark energy affects the expansion of the universe, while dark matter affects the rotational speeds of galaxies. They do not interact with eachother
6. What If We Could Harness The Power Of Dark Matter/Energy? If we could harness the power of dark matter or dark energy, some scientists predict super-human powers and time travel.
